我在向我的簡單項目添加 AOP 功能時出現以下錯誤，有人可以為我解釋一下嗎？我還在下面提到了代碼的相關部分。Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.AOP.Car' available    at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:346)    at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:337)    at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1123)    at com.AOP.App.main(App.java:13)package com.AOP;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;    @Configuration@ComponentScan(basePackages = "com.AOP")public class AppConfig {        }package com.AOP;import org.springframework.context.ApplicationContext;import org.springframework.context.annotation.AnnotationConfigApplicationContext;public class App {    public static void main( String[] args )    {        ApplicationContext context = new  AnnotationConfigApplicationContext(AppConfig.class);        Car car =  context.getBean(Car.class);              car.drive();    }}package com.AOP;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;@Componentpublic class Car implements Vehicle{    @Autowired    private Tyre tyre;          public Tyre getTyre() {        return tyre;    }    public void setTyre(Tyre tyre) {        this.tyre = tyre;    }    public void drive()    {        System.out.println("driving a car");        System.out.println(tyre);    }}package com.AOP;public interface Vehicle {    void drive();}如果我在沒有實現“Vehicle”接口的情況下得到一個簡單的類“Car”，那么一切正常。但是添加該擴展名將導致 menterror。
